[0045] Embodiment

[0046] This embodiment provides a separable connector. Refer to Figures 1 to 3 , the separable connector includes a pin-end insulator 1, a socket-end insulator 2, and a conductive pin 3. The socket-end insulator 2 is inserted and matched with the pin-end insulator 1. An open area 22 is provided on the end face of the socket-end insulator 2 facing the pin-end insulator 1. The open area 22 is used to arrange a corresponding circuit board to configure other components and welding wires, such as a processing chip, etc.

[0047] In this embodiment, refer to Figure 3 and Figure 4 , a plurality of conductive pins 3 are provided. One end of any conductive pin 3 is installed in the pin-end insulator 1, and the other end is adapted to be inserted into the socket-end insulator 2. Any conductive pin 3 is arranged to avoid the open area 22 to reserve an installation space for components. The pin-end insulator 1 is provided with an alignment area 14, and the alignment area 14 and the open area 22 are correspondingly arranged. Correspondingly, the conductive pin 3 is arranged to avoid the alignment area 14.

[0048] Regarding the structure of the open area 22, in some embodiments, refer to Figure 3 , the open area 22 can be set as the side wall surface area of the socket-end insulator 2 facing the pin-end insulator 1. The open area 22 extends from the outer edge side of the socket-end insulator 2 to the inner edge side of the socket-end insulator 2.

[0049] In one embodiment, after the pin-end insulator 1, the socket-end insulator 2, and the conductive pin 3 are assembled, there is an interval area space between the open area 22 and the alignment area 14, and the interval area space can be used for the installation of components.

[0050] In another embodiment, after the needle - end insulator 1, the hole - end insulator 2, and the conductive needle body 3 are assembled, there is no spacer region space between the open region 22 and the alignment region 14.

Under the condition of meeting the insulating gap, a suitable spacing distance is selected between two adjacent conductive needle bodies 3. Among them, the insulating gap enables the adjacent conductive needle bodies 3 not to interfere with each other's conduction states. The insulating gap needs to be specifically configured considering factors such as the material of the conductive needle bodies 3, the electrical conditions conducted by the conductive needle bodies 3, and the assembly space reserved on the insulator, and is not specifically limited in this embodiment.

[0061] In a specific embodiment, the heat dissipation channel 13 is constructed on the pin-end insulator 1, and a heat dissipation path is provided on the pin-end cover plate 4, and the heat dissipation path is communicated with the heat dissipation channel 13. The heat dissipation path and the heat dissipation channel 13 are used to dissipate heat from the components and conductive pin bodies 3 configured in the open area 22, so as to reduce the operating temperature inside the connector and improve the stability of power supply and signal transmission operations.

[0062] As an exemplary embodiment, refer to Figure 5 and Figure 7 The heat dissipation path includes a heat dissipation groove 42 and a communication hole 45.

The conductive needle bodies 3 are connected in a staggered array on the hole-end insulator 2. Since each conductive needle body 3 is isolated by the hole-end insulator 2, the arrangement gap of the conductive needle bodies 3 can be minimized by the staggered array method. Under the condition of meeting the requirements of pin arrangement, an open area 22 can also be set to configure other components and welding wires, such as a processing chip, etc. on the circuit board corresponding to the open area 22.
